Malignant Eccrine Poroma of the Left Upper Eyelid Resembling Cutaneous Horn / 대한피부과학회지

ABSTRACT

Malignant eccrine poroma is a rare skin appendage tumor, originating from the intraepidermal eccrine duct. It develops either spontaneously or in an eccrine poroma of long-standing duration. It usually affects older people and is located most commonly on the lower extremities. We report a case of an 84 year old woman with a malignant eccrine poroma on the left upper eyelid, which resembled a cutaneous horn. She presented with a solitary, tender, firm, 0.4x0.4x0.9 cm-sized, silvery-white colored papule on the left upper eyelid. She was treated with surgical excision and to date shows no recurrence.
